Brief Discussion About GE Multilin 869 relay
The GE Multilin 869 relay is part of the Multilin 8 Series protective relay platform and is designed to safeguard, control, and manage medium and large induction and synchronous motors. The 869 has an integrated synchronous motor protection module for synchronous motor protection and control.
The Multilin 869 offers advanced capability for a variety of applications, including high-speed protection, broad programmable logic customization, advanced motor monitoring, and diagnostics, and flexible configuration options. The 8 Series platform’s advanced connectivity makes it simple to integrate into the process and electrical control systems for better asset monitoring and control. Retrofit kits have been produced to make the migration and upgrade from the current SR 469 protection relays as simple as possible.
Overview Of Motor Protection Relay
To provide optimal protection and ensure maximum process uptime, GE’s motor protection systems implement advanced thermal modelling. Moreover, our engineers and technicians are well-versed in motor protection and the different scenarios that can result in motor damage. They apply their knowledge to create some of the most advanced protective relays and also systems in the world.
Advanced GE Motor Protection System Monitoring & Diagnostics
The GE Multilin 869 motor protection system has an inbuilt, low-cost Monitoring and Diagnostics function that uses existing relay data without the need for additional devices, sensors, wiring, or training. Motor failures and malfunctions can wreak havoc on a process, resulting in revenue and material losses. Predictive maintenance and situational awareness of the motor’s operational condition. They can assist prevent unplanned downtime and energy waste, resulting in increased motor output and longevity.
Stator turn-to-turn faults, broken rotor bar detection, roller-bearing faults, foundation looseness, eccentricity, and misalignments are among the motor monitoring and diagnostic characteristics. The 869 uses advanced Motor Current Signature Analysis (MCSA) to continually analyze the motor current signature and detect when an electrical, thermal, or mechanical defect/failure state occurs in the motor based on predefined algorithms.
The Multilin 869 Motor Protection System is a management, protection, and control system for motors ranging in horsepower from medium to big. The 869 provides full protection and control for a wide range of motor types and loads. The 869 relay delivers faster current, voltage, power, and frequency protection elements. They are available with fast protection pass that runs every 1/8th of a cycle, reducing asset stress. The Multilin 869 supports the most recent standard communication protocols, such as IEC 62439/PRP and IEC 61850 Ed2. In conclusion, it makes it simple to integrate new or existing SCADA/DCS networks.
